fft filters meaning in Chinese
滤波器
Examples
- High computational burden algorithms such as fft filtering are avoided in the algorithm so that the algorithm is applicable to real time object counting systems
该算法避免了傅立叶变换滤波等计算量较大算法的使用，适用于利用图像处理进行目标实时点数的领域。 - High computational burden algorithms such as fft filtering were avoided in the algorithm , so that the algorithm is applicable to real time objects counting systems
该算法避免了傅立叶变换滤波等计算量较大算法的使用，适用于利用图像处理进行目标实时计数的领域。 - On the basis of previous work , we developed a new data processing system by use of dsp & oop . the new system overcame the problems existed in the old data processing system successfully , such as the bug which cause program dead loop when the data is too long , and the frequency leak due to principle limit of fft filter . in addition , we eliminated the measurement error brought on by phase warp
我们在前人的工作基础上，利用现代数字信号处理技术和面向对象的软件开发技术，统一了弹上黑匣子数据处理系统的操作平台，完善了转速、扫描角测试数据处理系统，修正了原有处理程序中的因数据长度过长而导致程序死锁的bug ；利用有限冲击响应( fir )滤波器，在滤去噪声的同时，有效地解决了矩形窗fft滤波的频谱泄漏问题；另外还解决了因相位偏差而导致的测试误差。
